Hi I am pretty new to electronics and was looking for a little direction. I am working on building a few H bridges to power a small stepper motor. This is the circuit I am working on. I am trying to use an arduino to drive the inputs.
The motor I am trying to power is 3v and draws 350mA. I am trying to figure out the proper input voltages and resister values for biasing the transistors. I have worked through it a couple of times but cannot get the circuit to work. Does each line of the stepper motor draw 350mA? Any input or suggestions would be greatly appreciated at this point.
